4 Meteor or shooting star is the visible path made by a object from space as it travels through a planet s atmosphere. Sophie DesRosiers, Planétarium de Montréal
5 QuickTime and a YUV420 codec decompressor are needed to see this picture. StarChild, NASA Meteor or meteorite? S. Eichmiller Meteorite breaking up as it travels through the atmosphere Peekskill Meteorite October 9, 1992 Peekskill, New York Bill Menke
6 Meteorites are objects from space (meteoroids) that reach a planet s surface. Boy hit by a meteorite Uganda, Africa Dutch Meteor Society Rudolf Reiser R.A. Langheinrich Meteorites Collection Iron meteorite Arizona Largest meteorite discovered on Earth Namibia, Africa
7 Space dust NASA/JPL Cécile Engrand What are meteoroids? Meteoroids Asteroids NASA/JPL are particles of rock, metal and/or ice in space. Comets Pieces of other planets Rudolf Reiser
8 Most meteoroids are materials left over from the formation of our solar system 4.5 billion years ago! Don Dixon

26 Contact - Compression Meteoroid Planet surface Ejecta Shock waves Crater Formation: Planet surface 1. Meteoroid traveling kilometers/second strikes the surface of a planet 2. Shock waves compress the rocky surface and the meteoroid is vaporized Sophie DesRosiers, Planétarium de Montréal
27 Excavation Ejecta Planet surface Shock waves Crater Formation: Vapor Shock waves 3. Intense shock waves travel through the ground, breaking up and melting surrounding rock Molten rock Crater Ejecta curtain 4. Crater is formed as shock waves and ejecta expand outward Sophie DesRosiers, Planétarium de Montréal
28 Modification Fractured rock Ejecta blanket Crater Formation: Breccia Ejecta Fractured rock Fractured rock Uplifted rim 5. Shock waves die out and ejecta settles forming a blanket around the crater rim 6. Crater is fully formed and is modified by gravity, erosion and sedimentation over geologic time.

44 Impact craters help us understand: The geologic history and age of a planet s surface How geologic processes work on different worlds, and The importance of impacts in planetary formation and evolution
Introduction. Background
Introduction In introducing our research on mars we have asked the question: Is there a correlation between the width of an impact crater and the depth of that crater? This will lead to answering the question:
A geologic process An erosional force A chronological tool An influence on biology
